Linear Transmittance Filters

Linear transmittance filters are used for wavelength identification applications, employing a transmittance that changes linearly over a specified wavelength range. Their transmittance must be monotonic to provide a one-to-one correspondence between the filter transmittance and a given wavelength.

Iridian is experienced in the design and manufacture of numerous linear transmittance curves. They feature low etalon ripple, custom slope and dynamic ranges.
